ACRYLITE® LED color changing backlit black/white appears dark during the day and white at night. This is possible due to a special pigment formulation that yields 25% light transmittance. When backlit, this product appears dark and opaque without backlighting.

Traditionally, sign shops would apply a perforated film to a 2447 white sheet much like our original 9H04 SC P95 black/white version. Now with our 9K004 black/white sheet, it eliminates the need to buy this film, the time to apply it, and the worry about it weathering from the sheet in the field. This material is a “plug-n-play” option that offers much better light diffusion at minimal distances from the light source(s).

The illustration below shows how the acrylic stays dark during the day while allowing for the LED lights to glow at night.

LED color changing 9k004 operating principle

This sheet offers excellent solutions for the following applications:

  • Channel letter sign faces

  • Store fixture/retail displays
  • Special-effect luminous walls in architecture

ACRYLITE® black/white acrylic is an extruded sheet made at our Sanford, Maine plant. It cuts, bends and forms very easily. It is also extremely weatherable, making it great for outdoor applications and is 100% recyclable. For information and tips on how to properly clean, disinfect and maintain this sheet, click here.

Important guidelines to note:

  • This sheet works best when the edges are enclosed in the sign box or channel. There should be no overhanging edges if uniform appearance is desired.
  • The black and white sheet effect will be achieved regardless of which side is facing inward or outward. The sign surface will have a glossy appearance.
  • It is not necessary to add a separate diffusing panel to ensure that the image of the lamps is hidden when a standard distance from the lights are used. Alternately, a white vinyl diffusing film may be applied for enhanced diffusion when distance from the lighting source is close.
  • The intensity of effect can be adjusted by varying the positioning of the light source.
